随着显微外科技术的发展,现代显微外科手术显微镜已经应用于许多领域。先进的外科手术显微镜技术能够使医生更加清楚观察精细组织,完成各种显微外科手术,而这些手术是裸眼无法进行的。现在,手术显微镜已经成为一种重要的医疗设备应用于神经外科、耳鼻喉科、牙科,眼科等领域。 本文主要研究了一种新型的神经外科手术显微镜,主要的结果如下: 1.本文详细分析了手术显微镜的结构,提出了神经外科手术显微镜的总体设计计划和技术指标。 2.讨论了连续变倍光学系统的原理和现代立体显微镜的设计。 3.给出了立体助手镜的详细设计图例,并且分析了立体助手镜的装校。 4.重新设计了主显微镜观察镜,该观察镜具有12.5x目镜,可以在30°～90°之间改变观察角度。 5.设计了一套新的照明系统,采用柯拉照明技术集成于光纤照明系统。 6.图像处理工作站满足了外科医生对记录图像管理的需要,临床的图像数据更加易于交流。
Along with the technology development in microsurgery, modern surgical microscope has been applied in many fields. The technology of advanced surgical microscope can make the doctor observe the precise tissue construction more clearly, and complete all kinds of the micro-surgical operation relying on the naked eye can"t operate. Now the operation microscope have already become a kind of key micro-surgery medical treatment equipments applied in the effective demand of neurosurgery, E.N.T and dental surgery ect. This thesis has studied a kind of new neurosurgery surgical operation microscope. The main results are as follows: 1. The construction of surgical operation microscope is analyzed in detail, and the total design scheme and technique parameters are put forward. 2. The zoom optical system’s principles and constructions of modern stereo-microscope design are discussed. 3. The optical system design figures in stereo- assistant microscope are given in detail. And the stereoscopic assistant"s optics mounting way are researched. 4. A type of viewing tube for the main microscope have redesigned with high-eyepoint 12.5x eyepieces and 30°～90°tiltable tube. 5. A set of new illumination system has been designed adopting the koller illumination way incorporated in the fiber optic illumination. 6. The picture processing system work station satisfies the demands of the surgeon in the conservancy of the record image, clinical image datum of the photos can be exchanged more conveniently.
